AC blower motor normal replacement?

I have a 2006 Corolla and the AC blower motor is starting to go again. If I replace it, it will be like the third time in five years I’ve had it replaced. Is that normal? I think the last time I had it replaced, it came with a lifetime warranty but I need to find that paperwork.

I just had to have the blower motor replaced in my 2017 Toyota Sienna that has 35,000 miles on the odometer. The bearings developed a terrible screeching noise. On the other hand, the 2011 Sienna my son now owns has 140,000 miles on the odometer and has never had to have a blower motor. He also has the 2006 Chevrolet Uplander I used to own. It has traveled 250,000 miles and has never had to have the blower motor replaced. I had a 1978 Oldsmobile Cutlass Salon that I purchased new. I had the car less than a year and had only driven it 12,000 miles when the blower motor has to be replaced under warranty. That motor got noisy after a couple of years. I bought a replacement at NAPA. That blower motor was under the hood and was easy to replace–just a 15 minute job. The blower motor from NAPA had a lifetime warranty. I think I had two free replacement blower motors in the 33 years I owned that car.
Unfortunately, the blower motor on the Sienna is under the right side of the dashboard. At my age, I didn’t want to do the contortions do get under the dash to replace the motor, even though it didn’t appear to be a real difficult job.
On most modern cars, the blower motor runs most of the time and wears out faster than in the old cars that didn’t have air conditioning.

I have had 2 Studebakers, one VW, one Chevy , one Olds and about 15 Chrysler products.

I have never changed a blower motor. Heater cores yes but not blower motors.

I attribute that to the fact that only the GM products needed the blower on all the time for ventilation. On all the other cars, once you were moving at speed the ram effect gave you all the flow you needed. and I did not keep the GMs long because I could no stand them. The constant blower noise in the GMs really irritated me and all the ergonomics were wrong for me.The floors were too high, the seats too low, but I could no raise the seats because to see through the wiper arc I had to bend over with the seat on the floor. Also neither the Impala or the Intrigue had enough legroom and my knees were in the air with the low seat so I had no thigh support. Also the Impa;a was the worst winter handling car I ever drove. It had a constant side to side swaying action from the poorly designed rear suspension.
